MACHINE FOR WHITENING AND SOFTENING LEATHER.

SPECIFICATION forming part of Letters Patent No. 451,096, dated April 28, 1891.

7 Application filed December 29, 1890. Serial No. 376,014. (No model.)

To all whom it may concern.-

Be it known that I, PHINEAS W. WHITTIER, of North Andover, in the county of Essex and State of Massachusetts, have invented a new and useful Improvement in Machines for Vhitening and Buffing Leather, of which the following is a specification.

This improvement relates to the arrangement and construction of the cross-head and guide-bars of amachine for whiteningleather. As the cross-head and guide-bars are ordinarily constructed the former is tubular and the latter are round. The result is that the guide-bars soon wear and become loose in the cross-head, which, however adjustable it may be, cannot then fit the guide-bars and prevent their rattling. In this improvement the guide-bars are made hexagonal in cross-section and play in adjustable angle-shaped boxes in the cross-head, all as below described, with the effect of allowing ample opportunity for taking up the wear with no danger of the guide-bars becoming loose or rattling.

In the accompanying drawings, in which similar letters of reference indicate corresponding parts, Figurel is a side view of the cross-head and guide-bars of a machine for whitening and buffing leather embodying my improvement. Fig. 2 is a front View of the cross-head with the guide-bars in cross vertical section. Fig. 3 is an enlarged cross vertical section of a portion of the cross-head and one of the guide-bars therein.

The cross-head consists of two parts conne zted by i he connecting-bar A. Each of these parts comprises a hanger B, adjustable box 0, and adjustable plate D, constructed as shown and below described. Between the boxes C and the hangers B lie the guide-bars E, on which the cross-head slides. These guide-bars are hexagonal in cross-section, are

stationary, and are supported by the frame H in the ordinary manner. The two lower surfaces of the hexagonal guide-bar E fit against the corresponding inner surfaces of the angleshaped beds of the hangers B, while the two upper surfaces of the guide-bars fit into the inner surfaces of the angle-shaped boxes 0. The plates D rest on the boxes C and are secured to the hangers B by means of bolts I, adjusted by nuts K, said bolts extending through holes in the plates D into threaded holes in the parallel vertical sides 13 of the hangers.

It will readily be seen that as the hexagonal gnidebars E wear they only require the readjustment of the nuts K to prevent any looseness or rattling, and that this readj ustment can continue until the entire distance or width of the parallel vertical sides E of the bars are entirely taken up. It is evident, therefore, that the bars will wear a Very long time and that during all that time there will be no looseness or rattling.

The boxes O are provided with oiling devices L, which project through the plates D, and the hangers B are provided with the ordinary bearings N for the shaft of the driving-pulley.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

In a machine for Whitening and vbuffing leather, the combination, with the cross-head comprising the angle-shaped hangers B B and the angle-shaped boxes C, adj ustabl'y connected, as shown, of the hexagonal guide-bars E between said hangers and boxes and fitting Witnesses:
